I am thinking about buying a suppressor. I know I must complete ATF Form 4 and have my local "Sheriff or Police Chief" sign it. I live in Navarre, Santa Rosa County. Anyone had any problem getting them to sign it? I have read that they don't have to do it if they don't want to. Do I have to have the local county Sheriff to do it or can a Sheriff in another county (like Okaloosa) sign it? Can it be any Sheriff or is there normally a designated person? Any recommendation on a suppressor friendly Sheriff/Police Chief? I also read the benefit of doing it in a Trust, but now required the signature as well. Do you recommend that approve? What's the drawback? I do have a concealed carry permit. Thanks in advance.
